Peanut Inspector Certification Practice Exam

What information do inspectors use the Mechanical Screen Shaker to determine?

1. The moisture percentage of the peanuts

2. The size classification of the kernels

3. The presence of foreign materials

4. The overall weight of the batch

The correct answer is: The size classification of the kernels

The Mechanical Screen Shaker is utilized by inspectors primarily to assess the size classification of peanut kernels. This equipment operates by utilizing various screens with defined hole sizes, allowing different sizes of peanut kernels to separate according to their dimensions. By passing the peanut batch through the shaker, inspectors can effectively classify the kernels into different size categories, which is crucial for determining their market grade and ensuring compliance with industry standards. This classification plays a vital role in quality control, as different sizes may correspond to different uses or grade values in the market. Understanding size classification helps ensure that peanuts meet consumer expectations and fulfill specific commercial requirements. While moisture content, the presence of foreign materials, and overall weight are also important factors in peanut inspection, they are assessed using different methods and instruments. For instance, moisture content is typically measured with moisture meters, foreign materials are identified through visual inspection and additional cleaning procedures, and weight is determined using scales. Hence, the role of the Mechanical Screen Shaker is specifically aligned with classifying kernel sizes.
